I'm going to India for the first time ever, for a work conference. As it happens, an Indian former coworker of mine has a sister who is getting married the following week, and I've been invited to the wedding. Very exciting! A little advice on two points, please.

(1) Gifts - I'm under the impression that nice jewelry would make an appropriate gift. I live in Colorado and know a jeweler who makes beautiful western-themed items by hand. We're talking Native American-style pieces, in silver with turquoise or similar stones. I'm thinking a nice necklace as a gift for the bride. Is that enough? Would I need to bring a piece for the groom as well? Is that ok?

(2) What to wear? I'm female and don't own a sari; I was going to bring basically business-wear for work and casual stuff for travel. I will have nearly a week in Mumbai (for the conference) before flying to Delhi for the wedding, and I would love an excuse to buy a sari or two. Can I have something made in that time? Should I order something online here before I go? Do I need multiple outfits - one for each of the days of the wedding? How fancy does it need to be?

Any other things I should know? I'm feeling very lucky to have been invited.

Thanks for any advice!
